I waited for a medical doctor for an hour and a half (I had an appointment)
I wasn’t happy about it and only did it to get asthma meds I desperately needed

With t I think I’ve waited up to twenty minutes but without a text or email I think I’d only wait up to 15. And I’d text him “I’m here where are you?”

Anything longer than 30 minutes is disrespectful to a patient unless they make efforts at contact. Just my opinion.
